Today’s Outline
• The basics of exercise and adaptation• The recovery response• Eating to improve recovery• Training to improve recovery
3
Overload and Progression•For a body to make any positive modifications or adaptations it must be stressed above its normal working capacity.
•Only minor adjustments need to be made as the body can only repair, recover and adapt so fast.
•So with each adaptation there must be a new, increased level of stress if overload is to be applied.

Preventing Overtraining• Monitor client and look for signs of
impending issues• Properly progress clients
– Increase only slightly– Stay on program for a few weeks and do not
constantly change everything – allow your client to get good at something
• Train body parts/movements/etc. that are likely to be injured in sport or general activity

Maximizing Your GainsThe body is in a continuous state of protein turnover
Protein Synthesis – Protein Degradation= Muscle Growth

Recovery Nutrition
• Adequate and proper nutrition is the key to both endurance and strength and power performances– Effects on acute performance– Effects on recovery
• Decreased muscle damage• Increased glycogen storage
– Effects on subsequent performance
10
SPORTS DIET
• Fuels muscles for top performance• Nourishes the body• Optimizes health• Enhances recovery
11
•Muscle Protein Synthesis is greatly increased following resistance training rising rapidly and staying elevated for the first 24 hours, but by 36 hours has returned to baseline. The time course for elevated muscle protein synthesis following heavy resistance exercise.MacDougall JD, Gibala MJ, Tarnopolsky MA, MacDonald JR, Interisano SA, Yarasheski KE.
Muscle Protein Degradation is also elevated after resistance exercisesMixed muscle protein synthesis and breakdown after resistance exercise in humansS. M. Phillips, K. D. Tipton, A. Aarsland, S. E. Wolf and R. R. Wolfe
Protein Synthesis vs. Protein Degradation
12
The Response to Training
• Exercise creates a stress on the body• If the stress is applied properly the body
can recover and adapt to the training stress
• If the stress is misapplied the ability to recover and adapt is compromised and overtraining and injury occur

15
Response to Training
• The timing of training stimuli is a function of the athlete’s ability to recover between training sessions
• Proper recovery allows more frequent application of the training stimulus and greater improvements in fitness and performance
16
Recovery
• Recovery starts before the end of the workout
• Good nutrition during training enhances recovery after training – Prevents breakdown of muscle– Enhances protein synthesis
21
Dehydration Adversely Affects:
• Muscle strength• Endurance• Coordination• Mental acuity• Thermoregulatory processes

Rehydration
• Use of sport drinks enhances fluid intake– Water- 53% need is filled– Water + Glucose- 70% need is filled– Water + Glucose + Na, K- 75% need is
filled– The addition of protein can enhance fluid
retention even further
24
Rehydration
• Subjects exercised to dehydrate by 2.5% BW
• Post exercise consumed on of three drinks– 6 g CHO, 1.75g PRO, 45.8 mg Na– 6g CHO, 45.8 mg Na– Water
• Observed over three hours
27
During Exercise Nutrition
• Protein content– 1.5-2.2 g/ 100ml– Complete fast acting protein
• Whey protein
28
During Exercise Nutrition
• Best performances seen when 30-60 grams of CHO/hr is consumed
• Drink with 4-8g CHO/100ml provides adequate CHO without causing gastric emptying problems
29
Removal of Lactate
• Cool down following intense training• Low intensity aerobic training using
primarily slow twitch muscle fibers enhances clearance of lactate
• 10-15 minutes immediately following the training session
• Followed by full body static stretching for 10-15 minutes
30
Reducing Fatigue During Exercise
• A variety of nutrients and supplement have been used to try to decrease fatigue– Creatine – increases intramuscular CP
stores– Sodium Bicarbonate – helps maintain ph
levels– Caffeine – increases muscle activation
(Antonio, J., and Stout, J. Supplements for strength and power athletes. Human Kinetics, Champaign, Ill, 2002)

o Dunnett et al. 1999; Harris et al 2005 suggest that beta-alanine is probably the rate limiting substrate to carnosine synthesis
o A Study by Harris et al. (2005)• Males (18 - 21 years) that supplemented with
3 - 6 g/day of Beta-alanine showed significant increases in Type I and II skeletal muscle carnosine
• 64% increase in 28 days• No additional effect when adding L-Histidine or
Carnosine
Beta-Alanine Supplementation
32
Accumulated Metabolic Byproducts Can Lead to Muscle Fatigue and Impaired Function
• Acute intense exercise can result in the accumulation of Lactate and H+
in muscle with decreases in pH from 7.1 to 6.5 or lower (Pan et al. 1988)
• pH decreases and interferes with CA2+ release from the SR• pH decreases and directly affects actin-myosin affinity• pH decreases and interferes with ATP breakdown• pH decreases and interferes with ATP production by decreasing activity of
enzymes in metabolic pathways.
• Carnosine has a Pka value of 6.8 which allows it to function effectively as an intramuscular H+ buffer over the physiological pH range (Harris 1995; Sewell 1991)
• Suzuki et al. (2002) observed a significant relationship between[carnosine] in human skeletal muscle and high intensity exerciseperformance
33
Refueling
• Restoring muscle, and liver carbohydrate stores is the priority
• Refueling should begin immediately after exercise, within 15 minutes of finishing the session.
34
Refueling• The combination of
carbohydrate and protein post exercise promotes the fastest uptake of carbohydrate into the muscles
• The combination of carbohydrate and protein results in the greatest storage of glycogen
(Ivy et al. 2002 J. Appl Physiol. 93: 1337-1344)
35
Refueling
• The combination of protein and carbohydrate stimulates a greater insulin response (van hall et al J. Appl Physiol. 81:801-809, 1996; Van Loon et al. Am J. Clin Nutr. 72: 106-111, 2000)
• Insulin drives both carbohydrate and amino acids into the muscles and liver
• 1-1.5 g CHO/kg/hr during the initial 2 hours of the recovery period (Ivey, J. Glycogen resynthesis after exercise: effect of carbohydrate intake. Int J Sports Med. 19: S142-S145 1998)
36
Rebuilding
• The rebuilding of fatigued and damaged muscle tissue is essential for adaptations following training
• Immediately post exercise insulin helps stimulate the rebuilding process by transporting amino acids into the muscles
37
Rebuilding
• As little at 3 grams of EAA’s is enough to significantly increase protein synthesis (Miller et al. 2003)
• However, 6 grams of EAA’s has shown to maximally stimulate protein synthesis in smaller subjects.Borsheim et al. Am J Physiol. 283:E648-57, 2002
• 100 grams of CHO can increase protein synthesis by 35% but is not as effective as 6 grams of EAA’s (250%) (Biolo et al. 1997, Borsheim et al. 2003)

Timing is Everything
• Recovery drinks are most effective when taken immediately before and after exercise
• Masters athletes can see significant muscle mass increases by taking a carbohydrate/protein drink immediately post exercise.
40
Timing is Everything
• 13 men (74 yr of age); Trained them 12 weeks, 3 x per week with weights
• Took a liquid carbohydrate and protein meal
• IMMEDIATELY AFTER TRAINING • 2 HOURS AFTER TRAINING

Functional Adaptation• Functional Strains are the objectives and
stimuli for adaptation• Functional overload says that mechanical
loads stimulate bone modeling that is site specific
• Artificial Loading studies* show that bone is sensitive to magnitude and distribution of dynamic strains, but insensitive to static conditions
Lanyon, L, and Rubin, C. 1984. Static and dynamic loads as an influence on bone remodeling. Journal of Biomechanics, 16:897-905.
49
Exercise Adaptations• Exercise improves bone density and cortical thickness• Extensive remodeling may occur if initial bone matrix
structure is poor• Intensity, frequency, duration of exercise along with
skeletal maturity, type of bones and anatomical location all play a role in determining the extent to which bone can adapt
• Femoral bone (particularly its neck) strength appears to increase more than any other bone through vigorous exercise such as running or weightlifting
• Exercise above threshold elicits systemic remodeling responses that are specific to the task

Preventative Medicine• Examine the Injury History
– How it occurred– How long ago– What impact does it have on your training program
• Needs Analysis• Range of Motion
– Multiple Planes• Range in different planes
– Flexibility– Active Range
• Pre-Hab
51
Pre-Hab
• By Joint Vulnerability• By Load Distribution• By Force Output• By Speed• By Specific Muscles
– Acting as a braking mechanism

Key Concepts of Physiological Adaptations to Exercise Training
Each person responds differently to each training program.The magnitude of the physiological or performance gain is related to the size of an athlete’s adaptationalwindow.The amount of physiological adaptation depends on the effectiveness of the exercise prescriptions used in the training program.Training for peak athletic performance is different from training for optimal health and fitness.There is a psychological component to training.

57
The structural changes in motor units are not equal even given
the same Training. Why is this?• Not all motor units are recruited to the
same extent during training.• Motor units with different metabolic
profiles will exhibit different degrees of change to different training stimuli.
• All fibers in a motor unit may not be exactly the same structurally or biochemically.
Gardiner, P.F. Can. .J. Spt. Sci. 16(4):271-288.
59
Rep Speed• Slow Rep Training
– Possibly stimulates more fibers– May improve overall strength– Definitely helps control weight better which
translates to cleaner technique– May make you slower
• Fast Rep Training– Improves Neuromuscular Speed– Improves Synchronization– Improves Rate of Force Development (RFD)– May cause momentum and poor technique

Monitoring Recovery
• Questionnaire is the simplest method and almost as accurate as physiological measures such as Urea
• Use a scale of 1-10, half point are allowed
• Need two weeks of light training or rest to establish a baseline
72
Monitoring Recovery
• A change of more than two points on two or more items suggests an accumulation of fatigue that needs to be addressed
• Morning HR changes of more than 10 bpm for more than 3 days suggest fatigue.
